Vise did not work. There was no pin that would open the jaw along with the washer. I used a cotter pin to hold it in place. Also, the vise didn't rotate. The pivot slots on the cheek base were cracked due to the rough casting. I had to smooth out the grooves with a file to make it spin. I bought a vise thinking it was a good price but found that Lowes had a vise for sale for the same price but much better quality.
